Anchor configurations. (a) The three unique anchors found for PTCDA on Au(111), including their respective Voronoi diagrams. (b) The reachable areas for the three anchors. Red indicates possible lateral positions of the two Ocarb atoms when PTCDA is bound to the respective anchor (compare Figure 6b). These reachable positions are primarily defined by the intrinsic separation of the two Ocarb atoms (4.5 Å).
